Considering just the input box:

<input type="text" ID="tbx1" class="tbx1_default"
onmouseover="this.className='tbx1_hover';"
onmouseout="this.className='tbx1_default';" />

And its style:

.tbx1_default
{
border:1px solid #aaa;
height:16px;
width:250px;
padding: 3px;
}
.tbx1_hover
{
border:1px solid green;
height:16px;
width:250px;
padding: 3px;
}

The effect is still not the same, eg: the glow is too thin ... I tried 2px border, but it´s not the way to go ... probably what´s glowing is not the input border, but maybe something else???

To simplify things ... i´m not using bg images and discarded the image button as well

Maybe a div or span tag wrapping the input box and this div or span will hover?
